Chapter 761 (2/2)
”No wonder I didn't see him!” Yun Fei understood this.
Now he feels that he is a bit irresponsible as a boss.
This is a major event of their group company, but he was angry with the big leader and beat the table with the second leader before he grabbed the project. Since then, he has never been involved in this matter.
There are also people like Jiang Jianxing and Sun Lin, otherwise they would have been called to his office by the second leader. It's a good training!
”How many knives are designed for the tool magazine of our five axis machining center?” Five axis woodworking machine, Yun Fei is too lazy to see.
That thing is not mainstream.
If you want to do it, you have to do heavy five axes!
Of course, in line with the principle that no matter how small a mosquito is, it is also meat. The research progress of the 91 Research Institute in woodworking machines goes hand in hand with the heavy five axis linkage machine tools. In particular, the turn milling compound machining center supporting the Three Gorges has been successfully studied and put into use, which is absolutely of great benefit to them.
Especially in the design and manufacture of heavy multi axis CNC machine tools, otherwise Yunfei would not take the risk of offending the second leader and beat the table and the bench with them to rob the fat of the five Han heavy machine.
In front of this work area 2000 × The semi-finished product of the 1200 double spindle five axis vertical and horizontal dual-purpose Heavy CNC machining center, Yun Fei asked with a frown.
He insisted on this design. There is no such design in both the domestic market and the international market. Sun Lin was also very opposed to Yun's insistence at the beginning, but if he was the boss, he had to implement it, didn't he?
So, there is such a thing that subverts the traditional design.
This is Yun Fei's idea of making a living when he heard those teachers talking about doing some heavy parts when he was a technician. He didn't have a chance to test his idea before, but now, when he has a chance, he must let someone try it out.
It's his idea, the thing in front of him, which has cost more than 30 million!
This is a combination of a horizontal machining center and a vertical gantry machining center. It must look a little strange and awkward. The gantry type vertical machining center, that is, the upper spindle can move back and forth, while the column cannot move left and right. The left and right movement mainly depends on the workbench.
Both spindle systems use the same chain magazine.
This makes the design more difficult. It has been done for more than two years, and a lot of waste parts have made such progress.
”120 knives, but the two spindle heads you require can be processed at the same time. So far, it has not been realized. It is easy to interfere in the processing engineering. If our control technology has not made a breakthrough, you are not much better than the foreign processing center that can carry out vertical and horizontal conversion, Maybe users will despise this design because it is too cumbersome... ”For this, Deng Lanqing feels that Yunfei is a little whimsical.
This subverts the traditional design, but also because of this design, the volume of the whole equipment is one-third larger than that of the same type.
If we can successfully realize the simultaneous processing of double spindles, this design can be called a genius design. If we can't, it's a design that adds to the snake.
The volume is one third larger, but the manufacturing cost and manufacturing difficulty are more than double.
”Despise do not despise, this has to wait until the research is successfully introduced to the market, will know, don't draw a conclusion so early!” Sun Lin said dissatisfied with his closed door disciple.
The most fear of those engaged in research is to rely on their own judgment when there is no result.
”Double spindle can't be processed at the same time. What's the reason? Do they interfere with each other during processing, or the delay of the control signal? ” Yun Fei still knows a little about these things.
The main difficulty of this design of two spindles processing two different surfaces at the same time is in the two aspects he put forward. The problem of interference is still easy to solve, mainly because the two spindles cannot be synchronized.
The spindle above needs to move in one direction, while the horizontal spindle needs to move in another direction, which makes it very difficult to control in the processing process. If not, there will be a knife collision.
”Mainly control signal delay and large amount of data processing. At present, more than 400 32-bit industrial control chips are used on this equipment, which makes the control signal jump too many times... ”Sun Lin said with a bitter smile.
The boss moved his mouth and his men broke their legs
”Tanalia, the 64 bit chip hasn't been worked out yet?” Yun Fei asked with a frown.
How long have you been working on this chip?
”It's out, but the current performance is very unstable. Even if it's out, it's useless if our control system can't keep up. An old Cao has said many times that he wants to work hard for you...” Deng Lanqing said to Yun Fei with a smile.
Yunfei knew how to deceive Cao Zhijiang. As a result, the Institute was faced with the problem of developing several control systems at the same time.
This makes the old man's head big.
What the cloud can't do, that is, the three-axis system plagiarizes other people's designs.
In fact, it has been proved that the CNC system he made by copying several systems has no development potential at all, and he can't even continue to expand
Huadu CNC has made slow progress. For so many years, they have not launched their own high-end CNC system or improved four-axis or even five axis linkage control system based on the design of dragon CNC system.
The number of flowers was dented by Yunfei, a half hanging designer!
”...” cloud is not speechless.
”Do it slowly. Even if it is done, it is estimated that the market prospect will not be too big. This thing is too high-end...” Yun Fei comforted himself.
”You can't talk about high-end technology, but after you get it out, the price is definitely high-end...” for the idea of Yun Fei, Deng Lanqing looked at him once and laughed at him once.
”Don't worry, if it's really done, there will definitely be users. If it can't be sold, throw a few units into Lao Wang's xinkaixing, and then throw a few units into plant 132, Dongqi or something. The family asked them to get one or two back, and the cost will come out...” Yun Fei said with surprise.
In fact, the most important user of this design is the processing and production of high-precision heavy parts.
Yun Fei didn't even think about whether he could sell when he was opposed by Sun Lin at the beginning. This is one of his dreams!
Only by surpassing those foreign giants in design concept can we compete with them in technology.
”Xiao Yun, don't listen to Xiao Deng. A few days ago, Lao Huang, 132, came to us with a group of people to see the progress of five axes. He was very interested in this type of heavy machine tools, but he thought our processing scope was a little small...” Sun Lin also knew that the state-owned units were the main market users of these top machine tools.
The state-owned units that dare to buy such equipment will only care about the processing accuracy, performance and price, which are rarely considered.
This kind of machining center, for the processing of box parts and large molds, the efficiency will be more than twice that of ordinary machine tools! Moreover, the two spindles of the tool can call each other, which is absolutely an artifact for the processing of some complex parts.
”Oh? Which factory leader has such vision? ” For such a thing, Yun Fei really felt a little surprised.
”It seems that there is a gearbox factory in the mountain city and an automobile engine factory...”
Yun Fei nodded. Such potential customers must have a good relationship.
He doesn't worry about selling other five axis machining centers, but this one, but his boss Yunda's own design concept, if he can sell 30 or 50 sets, it will definitely make him happier than other five axis machining centers.
Several other models of five axis machining centers in the test workshop have basically been finalized. What we need now is to continuously improve the accuracy and carry out various tests. These are some technical problems that can not be solved by his half hearted boss.
From the four-axis machining center, the 91 Research Institute basically began to use money to smash technology.
Not enough researchers? Let Chen Jie smash it with money. As long as it's a really skilled person, give as much as you want. Of course, you have to make achievements!
Insufficient research funds? Let Zhang Cui transfer from my private account to the Research Institute. Can the richest man in mainland China have this money?
Not enough technology? There's no way
”By the way, cloud boy, have you considered the matter of building an underground research workshop?” Seeing that Yunfei was going to the flexible manufacturing test workshop, Sun Lin stopped Yunfei.
”What do you think? What is the use of the internal workshop in the mountain of the Jiuyuan base, or is it to build a workshop here underground? ” Yun Fei was stunned. He really didn't think about it.
